TECHNICAL FIELD

The present invention relates generally to a modular portable printerand more particularly to such a printer having interchangeable computerterminals pivotally attached thereto and other interchangeablecomponents for attachment thereto.

BACKGROUND ART

Hand-held terminals for receiving, storing and transmitting informationtypically do not have printers attached thereto. On the other hand,certain devices such as calculators often do have a printer built in tothe same housing as the calculator itself. There are so many differenthand-held devices, some of which need to eventually be connected toprinters and others which do not. The industry has generally designedterminals or the like to meet each different customer's needs. This hasresulted in thousands of products which are separately designed andmanufactured and which do not share common parts with other similarproducts.

The result has been higher manufacturing costs and consequently a highercost to the consumer than would be possible if some sort of modularityor an interchange of common parts could be used. Furthermore, if thecustomer decides to use different equipment, then this would often meanscrapping the previously used equipment and purchasing entirely newequipment.

Consequently, there is a need for a modular terminal and printer conceptwhich is configurable to the customers' needs and expandable by stillusing the same basic parts, but interchangeably adding other partsthereto as desired.

BEST MODES FOR CARRYING OUT THE INVENTION DESCRIPTION OF FIGS. 1-18

Referring now to the drawings wherein like reference numerals designateidentical or corresponding parts throughout the several views, FIG. 1shows a printer frame (10) constructed in accordance with the presentinvention. The sides of the frame (10) have elongated, dovetail in crosssection, portions (11) so that handles (12), which can containre-chargeable batteries, are selectively attached to or removed from theframe (10). An opening (13) is formed for receiving a printer and anopening (14) is formed for receiving a computer terminal or the like.

Referring to FIG. 5, it is noted that the frame (10) will receive aprinter back (17) and a printer top (18) or (19). The printer tops havelatches (21) thereon and two-inch paper slots (22) thereon, although theprinter top (18) could have a four-inch paper slot oriented at 90° withrespect to the paper slot (22) shown in FIG. 5. The printer top (19) hasa terminal display (23) thereon which may be used when the terminalitself does not have a display thereon. Similarly, when the terminal tobe used has its own display, then the printer top (18) would be used.

A printer bottom (15) or (16) can be pivotally attached to the printerframe (10) by threaded fasteners (20). A RAM card (25) and a ROM card(26) are receivable in the terminal bottoms (15) or (16). FIG. 5 alsoshows interchangeable terminal tops (30), which can have a drop-inkeyboard (31), top (32) which can have a drop-in keyboard (31), adocking unit (33), which can accept a hand-held terminal (34), apen-based tote or clipboard-type device (35), a device (36) withmagnetic card reader (52) and a drop-in keyboard (38) with display (39),a touch-screen device (41) and a top (42) for plugging in a standardcomputer (43) such as a Hewlett-Packard 95XL, or the like. All of thesetops (30), (32), (33), (35), (36), (41) and (42) can all be plugged intothe terminal bottom (16), for example.

Referring now to FIG. 6, it is noted that the frame (10) having handles(12) with re-chargeable batteries disposed therein is pivotally attachedto a bottom (16) of a terminal (30) with a touch screen. Threadedfasteners (20) achieve the pivotal attachment to frame (10) and arethreadably attached to the bottom (16) through the openings in the frame(10) which are shown in FIG. 1.

Referring to FIG. 7, it is noted that the printer bottom (17) isattached to the frame (10) and referring back to FIG. 6, it is notedthat the top (18) is also attached to the frame (10). This permitstwo-inch paper to be emitted from slot (22) and the plate (18) is heldin place by a latch (21) as discussed above.

Referring again to FIG. 7, it is noted that when the printer is in theposition shown in solid lines in FIG. 7, and the terminal (30) is in theposition shown in dashed lines in FIG. 7, this would correspond to thedevice being used on a desk whereby the terminal (30) can be easilyviewed and accessed and the paper (50) will pass out through the top ofthe printer slot (22). If, however, it is desired to carry the devicearound, it can be used in the position shown in solid lines in FIG. 7wherein the user's arm is under the bottom portion (17) and grasping theright side of the printer frame as shown in FIG. 7 with the forearmunder both the printer and the terminal (16) so that the other hand canaccess the terminal (30). Alternatively, to carry the device around anduse it, the user can move the printer to the dashed line position shownin FIG. 7 while leaving the terminal (30) in the position shown in solidlines in FIG. 16. This permits the user to put one hand between theterminal (30) and the printer (18), i.e., through opening (14). In thisway, the user can merely hold the terminal (30) with the printer hangingdown.

If it is desired to put the device shown in FIG. 7 on a person's belt,the belt loop device (70) shown in FIG. 17 can be used wherein the hooks(71) would go around the blank portion of threaded fasteners (20)between the head or handle thereof and the printer frame (10). It wouldalso be desirable, during such use, for the printer to be oriented sothat the paper (50) exits away from the person's body rather than towardit, whereby when viewing the device in FIG. 7 orientation with theprinter extending down, the person would be on the left of the devicewith the person's belt (72) having the belt loop device (70) attachedthereto. If the printer and terminal shown in FIG. 7 is to be mountedhigh on a shelf, for example in a van, then the printer would beoriented such that the paper tape (50) would extend downwardly and theterminal having bottom (16) thereon would then merely be positioned sothat it is in clear view of the user.

Referring now to FIG. 8, it is noted that the frame (10) has a printertop (19) with the display (23) thereon and a drop-in keyboard (31). Itis to be understood that this drop-in keyboard (31) can have the keysoriented in the direction shown or they can be oriented 90° with respectthereto, depending upon the customer's desires. A magnetic card reader(52) is attached to the terminal (32) for reading credit cards (53) orthe like by passing the credit card (53) through slot (54) in themagnetic card reader (52). Of course, the FIG. 8 structure can beoriented in any of the positions shown in FIG. 7, and of course, anyposition in between those positions shown in FIG. 7. The FIG. 8 drop-inkeyboard (31) uses hard keys (55) rather than a touch screen as is shownin FIG. 14.

Referring now to FIG. 9, it is noted that the frame (10) also has a top(19) with a display (23), but a docking unit (33) is rotatably attachedthereto by threaded fasteners (20). This docking unit has a hand-heldterminal (34) which snaps into place and automatically plugs into theprinter when it is snapped into the slot in docking unit (33). Thisterminal (34) can be one like the Norand Model 1600, Model 1100 or Model1000. The terminal (34) also has a display (57) so that the display (23)is somewhat of a duplication and the top (19) could be replaced by top(18) if desired; or if the terminal (34) does not have a display like(57), then the printer top (19) could be used instead.

FIG. 10 shows a typical orientation of the frame (10) with respect tothe docking unit (33), for example if it were used on a desk or layingon a seat of a van or the like. The device can be hand-held, it can bedisposed on a belt as shown in FIG. 17, or it could have a shoulderstrap or the like. As shown in FIG. 16, it could also be attached to avan by a bracket (65) having hooks (66) attached thereto and openings(67) for receiving fasteners which would go into the wall of a van orthe like. Referring back to FIGS. 9 and 10, it is noted that theterminal (34) can be removed and used in the many conventional ways thatsuch terminals are used, and when the printing capability is desired, itcan be reinserted into the docking unit (34) as shown.

Referring now to FIG. 11, it is noted that the frame (10) has printertop (18) attached thereto and a top (36) is attached to the bottom (16),which is, in turn, rotatably attached by threaded fasteners (20) to theframe (10). A drop-in computer keyboard (38) having a display (39)thereon, is the option chosen in FIG. 11. A magnetic card reader (52) isalso attached to the top (36) for reading credit cards (53).

Referring now to FIG. 12, it is noted that a pen-based tote board device(35) has a screen (61) thereon and a pen (62) disposed in a slot (63)having enlarged opening (64) on each end thereof. By pushing down on oneend of the pen-like device (62), it will be tipped up to the dashed lineposition shown in FIG. 18 and can be removed to use on the screen (61).This manual way of entering information into the terminal (16) permitsthe device to be arm holdable, hand holdable and permits use for eitherleft-handed or right-handed people. Buttons (59) on each side thereofcan be used for shift functions or to bring up programs or the like andcan be soft-labeled to add versatility to conform to what the customerdesires.

Referring to FIG. 13, it is noted that the device can be hand-held inthe position shown in solid lines in FIG. 13 by one arm, while writingwith the other arm of the user, or if the device is to be used on a deskor other surface like a desk, the tote board (35) can be tilted up tothe dashed line position shown in FIG. 13. If it is desired to removethe tote board device (35) from the printer, the terminal can be removedfrom the printer and used as a tote board-type device and thenreattached to the printer when printing capability is desired.

Referring now to FIG. 14, it is noted that the frame (10) has a top (18)attached thereto and a touch-screen display (41) is attached to theterminal bottom (16) shown in FIG. 5. The touch-screen device (41) isprogrammed so that by pushing one of the buttons (60) on each side ofthe touch-screen, the display will be oriented in one orientation or bypushing another one of buttons (60) in an orientation 90° from the firstsaid orientation whereby if a person desires to use the device on adesk, attached to a van either at a low position or a high position, thedisplay would typically be readable from the position shown in FIG. 14where the letters and numbers would be upright. However, if it isdesired to carry the device around, for example in the FIG. 7 positionwith the printer down and the person's hand through slot (14), or thedevice is to be worn on the belt (72) shown in FIG. 17, it may bedesired to re-orient the display on touch-screen (41) 90° so that thetop thereof is on one of the narrower sides of the touch-screen, ratherthan on the wider side of the touch-screen as previously described. Someof the function buttons (60) are also usable like the function buttons(59) whereby they can perform various shift functions or bring upvarious programs as desired.

Referring now to FIG. 15, it is noted that the printer frame (10) has atop (42) attached to the bottom (16) shown in FIG. 5 with an adapterplate for automatically plugging in a computer (43), such as aHewlett-Packard 95XL or the like, having a pivoted lid (44) with adisplay (45) therein. Since the computer (43) has its own display (45),printer top (18) would be utilized therewith. Of course, the computer(43) can be removed and used independently, or when it is desired tohave printer capability, it would be plugged in in the position shown inFIG. 15, into top (42) and bottom (16).

DESCRIPTION OF FIGS. 19-30

FIGS. 19-22 show a pen-based terminal (110) which is another embodimentof the pen-based device (35) shown in FIGS. 5, 12 and 13. FIGS. 23-25show a docking system (130) for use in conjunction with terminal (110).The docking system (130) is another embodiment of the dock (33) shown inFIGS. 5, 9 and 10. It is to be understood that the pen-based terminal(110) could be pivotally attached to the frame (10) (FIG. 1), or thepen-based terminal (110) could be received in the docking system (130)which could be pivotally attached to the frame (10) in a manner similarto that illustrated in FIGS. 12-13 and 9-10.

Referring now to FIGS. 19-22, the pen-based terminal (110) includes afront panel (111) having a number of function keys (112) and indicatorlights (113). A display (114) extends over a large area of the frontpanel (111). A light pen clip (115) is carried on the top edge of theterminal (110) to receive and secure a light pen (116) in position whennot in use to input data. A hand strap (117) extends from the top edge,over the back of the housing, then to the bottom edge of the terminal(110). A battery cover (118) encloses a section of the back of thehousing that carries a rechargeable battery (not shown).

The vehicle mount (150) has a base (151) that carries a connector (152)and a pair of locator pins (153) that matingly engage a connector (145)and locator openings (146) of a portable dock (140). The base (151)houses a transition cable assembly (154) that operably interconnects theconnector (152) to a power cable (155) and data cable (156) that extendfrom the base (151). Side panels (157) extend up from each side of thebase (151) and pivotally attach to a U-shaped bracket (158) attached toa vehicle (170). An arcuate slot (159) in each of the upwardly extendingarms of the bracket (158) receives a threaded rod (161) extending fromeach of the side panels (157). A locking wheel (162) is attached to theportion of each rod (161) extending out from the arms of the bracket(158).

Although the bracket (158) is typically mounted in the delivery vehicle(170), it is understood that it could likewise be located in a homeoffice, or even a depot environment with multi-dock capability. Thevehicle mount (150) could, for example, be configured to quickly detachfrom the bracket (158) and be used in a home office so that only one setof charge control systems, indicators, etc. would be required. As seenby reference to FIG. 25, the vehicle mount (150) is pivotally movablethrough the range of the arcuate slot (159) to conveniently position thedocking system (130) for the user. Once positioned as desired, thelocking wheel (162) is tightened to secure the docking system (130) inposition. The vehicle mount (150) selectively receives the portable dock(140) which in turn selectively receives the pen-based terminal (110).

The pen-based terminal (110) is operably connected to both the powercable (155) and the data cable (156) through a connector (121) ofadapter (120), the connector (145) of the portable dock (140), and theconnector (152) of the vehicle mount (150). Attachment to alternativeperipheral devices for processing information from and inputinginformation through the pen-based terminal (110) is illustrated in theschematics of FIGS. 27-30. A connector (123) is positioned on theadaptor and the docking system (130) is configured so that the scannerand DEX cables may remain connected to the pen-based terminal (110) whenthe terminal (110) is positioned in the portable dock (140). Also, thecharging system defaults to charge the battery in the terminal (110)first, and then to charge a spare battery (148) in the portable dock(140).

DESCRIPTION OF FIGS. 31-33.
